Amiga 3000 video strangeness

I just got an original Amiga 3000 working. It's a really old A3000 with
16 MHz m68030 and m68881. I want to get NetBSD running on it because I
don't have any other m68030 NetBSD machines, so I built a minimal kernel
and tried to run it. However, after it loaded, it started printing text is
a very peculiar way:

One can see that the machine has paniced; I had used a userland which was
created with m68060 optimizations, so that is most likely why.

I've now built a kernel that defaults to the serial console and will test
that in a little bit, but I thought I'd mention this in case there's a
chance that someone broke something with regards to ECS / OCS support or
in case someone has another machine to test. This is the latest NetBSD 4
tree.
